In February 2011, Hetzner.de added a funky bit of functionality to their hosting panel which made me rejoice - the ability to create a virtual MAC address for your extra IP addresses! As Hetzner are very restrictive in which NICs can use which IP addresses based on their MAC address, getting a Virtual Machine online in Bridged Mode was very hard, if not impossible.

This is a guide that will teach you not only how to create your own preseeded Ubuntu installation ISOs, but also how to get your Virtual Machines online with Hetzners EQ root server range.
